Mary Lou Fusi, the delivery nurse who helped bring Mac into this world, said she is still supporting him now. "I'm the one who caught him when he did his first flip, I think," Fusi said. "Go Mac. Do your best," she added.

Another freestyle skier from Madison at the Olympics is Kiley McKinnon, who went to school with Mac.

"We think of her as our best friend and she's so goofy, you know.," said McKinnon's friend Hannah Johnson.

She's so funny and we have such a strong relationship with her, that we don't even think 'she's competing in Pyeongchang South Korea," added friend Lauren Gallagher. "We're so excited to see you jump and we know you're going to do great," she said.
